Summary:Apparatuses and methods for time-of-flight mass spectrometry providing effective pulsed conversion of continuous ion beams into pulsed ion packets is disclosed. Bunching of energetic continuous ion beams forms ion packets, which are filtered by a subsequent isochronous energy filter. The bunching method is particularly suitable for ion sources with relatively large spatial emittance, otherwise unable to fir the acceptance of orthogonal accelerators. The method is particularly suitable for multi-reflecting TOF MS, which accommodates small size ion packets and where the duty cycle advantage of orthogonal accelerators is minor.
